Master-Slave Parallel Overview
Background When connecting the PSU power supplies in
parallel, up to 4 units can be used in parallel
and all units must be of the same model with
similar output settings.
To use the power supplies in parallel, units
must be used in a “master-slave” configuration.
In the master-slave configuration a “master”
power supply controls any other connected
“slave” power supplies. In order for the master
unit to control the slave units, the master unit
must use the analog control connector to
control the slave units.
When using the Analog Control Connector, the
connector must be wired correctly between the
master and each of the slave units. For the
complete connector pin assignment, see page
115, or alternatively, the PSU-01C, PSU-02C and
the PSU-03C cables can be used to connect a
master to unit to 1, 2 or 3 slave units,
respectively.
